Sedan

The First Battle of Sedan in 1870 sealed the fate of the Second French Empire and paved the way to the foundation of the German Empire, leading to the subsequent annual celebration of "Sedan Day" in Germany. The Meuse–Argonne offensive saw France, boosted by American reinforcements, reclaim Sedan from German forces towards the end of World War I. The Second Battle of Sedan in 1940 achieved a decisive breakthrough by Wehrmacht forces in the Battle of France and ultimately led to the collapse of the French Third Republic.

The town is situated about 200 km from Paris, 85 km north-east of Reims, and 10 km south of the border with Belgium. The historic centre occupies a peninsula formed by a bend in the river Meuse. Sedan station has rail connections to Charleville-Mézières, Reims and Longwy. The A34 autoroute links Sedan with Charleville-Mézières and Reims.

Sedan was founded in 1424. In the 16th century Sédan was an asylum for Protestant refugees from the Wars of Religion. Until 1651, the Principality of Sedan belonged to the La Tour d'Auvergne family. It was at that time a sovereign principality. Their representative, Marshal Turenne, was born at Sedan on 11 September 1611. With help from the Holy Roman Empire, it defeated France at the Battle of La Marfée. Immediately after its victory, Sedan was besieged and its prince, Frédéric Maurice de La Tour d'Auvergne, duc de Bouillon, submitted to France. It was annexed to France in return for sparing the prince's life after he became involved in a conspiracy against France. Sedan was the birthplace of Jacques MacDonald, a general who served in the Napoleonic Wars. In the 1840s, American composer-pianist Louis Moreau Gottschalk got his start in Europe with a successful concert in Sedan, including the original piece "Souvenir des Ardennes." During the Franco-Prussian War, on 2 September 1870, French emperor Napoleon III was taken prisoner with 100,000 of his soldiers at the First Battle of Sedan. Due to this victory, which made the unification of Germany possible, 2 September was declared Sedan Day (Sedantag) and a national German holiday in 1871. It remained a holiday until 1919. Sedan was occupied by the Germans for four years during World War I. On 13 November 1917, the German Crown Prince paraded the 13th Infantry Division over the course of "d'Alsace-Lorraine". From May 12 to 15, 1940, during World War II, German troops invaded neutral Belgium and crossed the river Meuse by winning the Second Battle of Sedan. The battle allowed them to win the Battle of France by bypassing the Maginot Line, which was the French fortification system, and entrapping the Allied Forces that were advancing east into Belgium, as part of the Allied Dyle Plan strategy.

Today Sedan is known for its castle, which is claimed to be the largest fortified medieval castle in Europe with a total area of 30000 m2 on seven levels. Construction started in 1424 and the castle's defences were constantly improved over the ages. It is the only remaining part of the once enormous fortifications in and around the town. • Illustration — Sedan Castle • Illustration — Central courtyard of the castle • Illustration — War memorial at the castle's Turenne gate
